Concentration of angiogenic factors in human mesenchymal stromal cell supernatants. In this study we quantified angiopoietin-1, angiogenin, thrombospondin-2, VEGF, aFGF, PLGF, endostatin. Values are expressed as average ± standard deviation of three replicates. Statistical significance difference was determined by analysis of variance followed by the Bonferroni post-hoc test (n = 3, α = 0.05). BM-MSC: bone marrow-derived mesenchymal stromal cells, AT-MSC adipose tissue-derived mesenchymal stromal cells, WJ-MSC: Wharton’s Jelly-derived mesenchymal stromal cells.
